Recently picked up and 06 Jetta tdi. Had a p0201 code when I got it. Drove it 30 miles with no issue. All of the sudden when I stopped to make a left turn it started to misfire. Looked at the wiring and found frayed wires. Do I need to replace this section of wire? Or can I just “clean” them up and heat shrink them?

Wired in new plug still having same issue. Just tested the wiring under the valve cover. Injector harness at cylinder 1 read 0.1 ohms at both wires. The injector itself read 0.2 ohms.

Cylinder 2 injector also read 0.2 ohms. I’m not sure if this is correct or I got a bad reading.

Tested all other wires in injector harness and they are all reading 0.1 ohms.

When I was driving it today to see if the new plug fixed it, it threw the P0201 code and started to misfire. I cleared the code while driving and the misfire went away. I’m at a loss on where to look next.

Swapping 1&2 injectors would narrow it down to the injector.
